Wifi has become incredibly common within the last ten years - free wireless internet connectivity is now available in just about every cafe, airport, restaurant, school and hotel. This means that if you live in a densely populated area, you spend most of your day surrounded by invisible signals passing information back and forth at unfathomable speeds. Not that being surrounded by these waves is anything new to most people - similar signals have been used by devices like radios, walkie-talkies and cell phones for the same kind of data transmission for even longer. The main difference between the transmissions sent off by your router and the ones coming off your phone is that Wifi operates at a much higher frequency (common ones being 2.4Ghz to 5Ghz) that allow much greater amounts of information to be transferred much quicker. With minimal interference, most household routers can transfer data at a rate of up to 54 megabits (bits, not bytes - bytes are bigger) of data per second. The faster this transfer speed is, the less you can blame your poor Team Fortress 2 performance on lag. -- source link
